My apologies to ShoreLines subscribers, there are problems with the FeedBlitz system that seem to be impacting our newsletter delivery. When we try to put out a newsletter we get just a blank page instead of content. Their weblog indicates that they've been working on this problem for about a week, so it must be a fairly serious issue. Hopefully we can restore service some time soon.
UPDATE: One blog post later, problem solved. Social media is great.
